James Gandolfini’s shocking death happened in the middle of a “guy’s trip” for the actor and his teenage son, Michael … TMZ has learned.

Multiple sources tell us James’ trip was for pleasure and business — first getting to spend some QT in Italy with Michael, who just recently graduated from the 8th grade … and then attending the Taormina Film Festival in Sicily.

We’re told Michael’s mom — James’ first wife Marcy Wudarski – immediately flew to Italy on Wednesday to be with her son … after she was told James had died.

James and his son were very tight — Michael is a big hockey fan, and he and his father were regulars at LA Kings home games.

You are a very sick person . He does have kids . Maybe your kids would be better off if you died ! You must be some role model for them . You are a disgrace . It’s a sad day when small children lose a parent under any surcumstanses . This is a good site when you stay off it !
